Infrared clinical thermometer

Abstract

The present invention discloses an infrared clinical thermometer, which comprises a casing, a temperature-sensing unit at one end of the casing, and a display unit on the casing, wherein the current and former measurement results are simultaneously presented on the display unit to facilitate the comparison of the measurement results.

1 . An infrared clinical thermometer comprising:
 a casing;   a button unit on said casing;   a temperature-sensing unit at one end of said casing and used to measure temperature;   a control circuit coupled to said button unit and said temperature-sensing unit, triggered by said button unit to start said temperature-sensing unit to perform a temperature measurement, and receiving a result of said temperature measurement from said temperature-sensing unit; and   a display unit on said casing, coupled to said control circuit, and presenting on a same picture both said result of said temperature measurement and a result of a former temperature measurement.   
   
   
       2 . The infrared clinical thermometer according to  claim 1 , wherein an infrared temperature sensor is inside said temperature-sensing unit. 
   
   
       3 . The infrared clinical thermometer according to  claim 1 , wherein said control circuit is coupled to a memory for storing results of temperature measurements. 
   
   
       4 . The infrared clinical thermometer according to  claim 1 , wherein said display unit is a liquid crystal display device. 
   
   
       5 . The infrared clinical thermometer according to  claim 1 , wherein said result of said temperature measurement is presented at a first position of said display unit, and said result of said former temperature measurement is presented at a second position of said display unit.
